4-53.

Draw a horizontal line through the center, top, and bottom of the curve.

The amplitude is from the middle up to the top of the curve.

The period is the length of one cycle. In this case it is 2*π*, so *F* = 1.

Shifts: Horizontal (left or right shift from *y*-axis). Vertical (up or down shifts from *x*-axis.)
